Fiber Bragg Grating
Based Sensors

FBGS is a Germany/Belgium based engineer and maker of high quality Fiber Bragg Gratings (FBGs), Interrogators, Sensors, and uniquely crafted fiber optic detecting arrangements. FBGS has created two extraordinary and completely robotized creation measures for FBGs which bring about exceptionally high caliber and savvy detecting parts with special optical and mechanical attributes. FBGS’s items are appropriate for both norm and bespoke applications in enterprises, for example, clinical, composite, transport, measure, common and geo, telecom and R&D. FBGS supplies ‘Draw Tower Gratings’ – DTG® and ‘Femto Second Gratings’ – FSG® as an OEM part and our items would find in numerous applications and items created by our clients around the world.

FBGS understands the interconnectibility and need of human mind to be connected with each other which led to the rapid development of increasing need for various sensing solutions. Allowing to measuring a variety of parameters in a broad range of applications. The shortcomings and drawbacks of existing systems paved the way for new developments. Optical fibers are light weight, passive and unobtrusive sensing wires with a thickness comparable to a human hair. Sensing features can be tailored to the needs of the application and the unprecedented multiplexing capabilities allows to move away from traditional discrete measurement points to continuous measurements visualizing strain and temperature gradients, pressure, multi-directional force, curvature and shape information.

Product Specifications

Draw Tower Gratings

We offer three types of DTG® with unique characteristics compared to classically produced FBGs, such as extremely high breaking-strength, spliceless array configuration and uniform coating coverage. FBG parameters and coating material can be selected based on customer needs.

Femto Second Gratings

The featured FemtoSecond Grating (FSG®) is a uniform apodized grating fabricated with ultra-short laser pulses, using a special through-the-coating inscription technique. The inscribed FSG® maintains the pristine high strength of the optical fiber and adds new performance features.

All Grating Fibers

The All Grating Fiber (AGF®) is an optical fiber containing densely spaced low reflective (R<0.1%) Draw Tower Gratings (DTG®s). The spatial separation from the center to center can be as small as 10mm and the FBG length can be chosen such that more than 95% of the fiber contains gratings.


Optical fiber sensors present undeniable advantages such as high fatigue limits, multiplexing and immunity to electromagnetic interferences. With our variety of high quality Fiber Bragg Grating sensors you are able to measure strain, force, temperature, pressure and shape.
